(INDIA) — India’s Income Tax Department has mandated that only `Form 16` and `Form 16A` downloaded from the TRACES portal are valid for filing income tax returns, a rule now in force as taxpayers begin filing for Assessment Year 2026–27.

The department said certificates generated through the portal “alone constitute valid and authentic TDS certificates.” It also told taxpayers, “Taxpayers are advised to ensure that the TDS certificates used for filing Income Tax Returns are obtained only from the official TRACES system.”

As of May 19, 2026, the requirement applies to salary tax deduction certificates in `Form 16` and non-salary certificates in `Form 16A`. The department said TRACES authentication makes the documents verifiable because each carries a Unique TDS Certificate Number and a TRACES watermark.

TRACES, short for TDS Reconciliation Analysis and Correction Enabling System, is managed by the Centralized Processing Cell, or CPC-TDS. It serves as the official platform for reconciling Tax Deducted at Source and Tax Collected at Source, and the Income Tax Department has positioned it as the only authorized source for valid TDS certificates.

Certificates produced manually, through accounting software, or by Excel utility do not meet that standard. Under the department’s framework, those versions are invalid even if they contain the same income and deduction figures.

The timing matters for employers because deductors must issue `Form 16` to employees by June 15, 2026. Missing that deadline with a TRACES-downloaded certificate can trigger a penalty of ₹100 per day for each certificate.

That deadline sits within a broader shift under the Income Tax Act, 2025. Starting in Tax Year 2026–27, `Form 16` is transitioning to `Form 130`, but the requirement for TRACES-level authentication remains in place whether the certificate uses the old or new form number.

The change gives the Income Tax Department tighter control over document authenticity at the point taxpayers file returns. By requiring documents downloaded from one system, the department ties each certificate to a record that can be checked through a unique identifier instead of relying on employer-generated versions.

Indian nationals dealing with U.S. immigration procedures face an added layer of consequence because 2026 rules in the United States place more weight on authenticated financial records. USCIS and the Department of State expanded financial vetting this year for H-1B, L-1, and Green Card applicants, categories in which tax records often support proof of income and employment history.

That reaches beyond return filing. Official Indian tax certificates such as `Form 16` and `Form 16A` are often used in Affidavits of Support on `Form I-864` and in employment-based petitions, which means the difference between a TRACES version and an employer-prepared version can matter outside India’s tax system.

USCIS also issued the “Hold and Review” Policy Memorandum, `PM-602-0194`, on January 1, 2026, directing officers to place holds on applications that contain inconsistent or unverified foreign documents. Under that policy, a `Form 16` without the official TRACES watermark or Unique ID may be treated as a fraud risk, tied to the [USCIS newsroom](https://www.uscis.gov/newsroom).

Indian nationals in the United States on F-1, J-1, or H-1B visas also use these records for tax purposes there. Authenticated certificates are needed to support a Foreign Tax Credit claim on U.S. `Form 1116`, which is used to avoid double taxation on income taxed in India and the United States.

Consular processing can bring the same documents under scrutiny. U.S. consulates in India, including posts in Mumbai and Delhi, may look to the [Department of State Reciprocity Table](https://travel.state.gov/content/travel/en/us-visas/Visa-Reciprocity-and-Civil-Documents-by-Country/India.html) for official civil and tax records, and non-TRACES certificates may lead to 221(g) administrative processing delays.

Applicants dealing with visa interviews or document requests often assemble tax records long after the original filing season has passed. In that setting, a TRACES-authenticated certificate gives officers a document with a traceable number and watermark instead of a payroll printout that may not match India’s official verification system.

The department’s mandate also sharpens the role of the TRACES portal in the annual tax workflow for employers and payroll teams. A business that still relies on software-generated certificates or manually prepared statements now risks not only non-compliance under Indian tax rules but also complications for employees who later submit those papers in overseas immigration or tax matters.

Nothing in the department’s language leaves room for parallel formats. Its message is that validity rests on origin, not appearance: `Form 16` and `Form 16A` count only if they come from TRACES, carry the Unique TDS Certificate Number, and bear the watermark the system applies during generation.

Taxpayers and deductors can obtain the certified forms through the CPC-TDS system, while broader tax guidance remains available through the Income Tax Department’s portal. People preparing visa or consular filings can also check U.S. Embassy in India consular services and the State Department reciprocity guidance, where an authenticated tax certificate can mean the difference between a complete file and one set aside for review.
